钙钛矿太阳能电池的吸收层具有高浓度的可移动离子空位。这些空位在相邻的晶格点之间进行热激活的跳变。由于钙钛矿材料固有的柔软性，离子跳变的移动空位浓度N0比大多数其他半导体中看…

k-Space首席执行官Darryl Barlett：“ k-Space和Veeco在分子束外延（MBE）沉积市场上有着长期成功的合作伙伴关系。我们与Veeco紧密合作，提供了直接与Veeco的控制软件进行通讯的现场测量工具，从而为…

The performance of all solar cells is dictated by charge recombination. A closer to ideal recombination dynamics results in improved performances, with fill factors approaching the limits based on Shockley–Queisser analysis. It is well known that fo…

There is increasing evidence that the presence of mobile ions in perovskite solar cells can cause a current-voltage curve hysteresis. However, it is still subject of ongoing debates how exactly mobile ions influence the device operation. We use drift-…

We report the development of highly efficient and stable solution-processed organic light-emitting transistors (OLETs) that combine a polymer heterostructure with the transparent high-k dielectric poly(vinylidenefluoride0.62-trifluoroethylene0.31-chlo…

Organic light-emitting diode (OLED) technology is promising for applications in next-generation displays and lighting. However, it is difficult especially in large-area mass production to cover a large substrate uniformly with organic layers, and vari…

The tandem architecture for perovskite solar cells has proven successful in promoting the development of such cells. A low-bandgap perovskite solar cell, which typically acts as a back cell, is one of the critical components for tandem perovskite sola…

Single‐carrier devices are perfect model systems to extract material parameters for more complex multilayer organic light‐emitting diodes (OLEDs) and to learn about charge transport and injection properties of the device. By combining simulation a…
